In PDF 32000-1:2008 a print PDF names its target condition through an output intent (subtype GTS_PDFX for PDF/X): OutputConditionIdentifier is required, and a DestOutputProfile ICC profile is given when the condition is not a registered standard. PDF has no selector among several intents; which one to use is for the buyer and printer to agree. An ICC profile embedded inside a placed image is normally ignored in rendering, because the PDF colour space entries govern. That PDF/X-4 requires an output intent is stated by the Library of Congress summary; ISO 15930-7 itself was not read. Whether a printer accepts RGB or requires CMYK is a contract matter.
